Improvement in sash-fasteners



UNITED STATES PATENT OEEICE.

SAMUEL G. RICE, OF ALBANY, NEW YORK, ASSIGNOR TO I-IIMSELF AND HEZEKIAHDODGE, OF SAME PLACE.

IMPROVEM ENT IN SASH-FASTEN ERS.

Specification forming part of Letters Patent No. 33,869, dated December3, 1861.

To all whom t may concern: i

Be it known that I, SAMUEL G. RICE, of the city of Albany, State of NewYork, have invented a new Catch for Securing Window- Sashes, which Icall Rices rotary sash and blind holder and fastener; and I declare thefollowing` specification, with the drawings accompanying it and formingpart thereof, to be a full and perfect description ot' my invention.

i Figure l represents the catch with its faceplate removed in order toshow its interior mechanism. Fig. 2 represents the catch attached to awindow-sash.

Similar letters in both figures denote the same parts of the apparatus.

This is an improvement upon that class of sash holders and fastenersattached to the stile of the sash and operating` against the sash-frame,and is constructed as shown in Fig. l.

A A is a shallow box, like an ordinary desk or drawer lock frame,intended to be sunk flush within thesash-stile, as shown in Fig. 2.

B is a toothed wheel, so placed that its cogs as they revolve shallproject just beyond the outer edge D of the sash-frame. A bent lever Lis pivoted at ct, its .upper limb being fitted with two teeth, forming ajaw or grip holding upon a tooth of the Wheel, so as to block itsmovement. A spring S is so xed to the frame as to maintain the jaw uponthe tooth.

Thelower part of L projects backward through the frame, forming afinger-piece F, by pressing upon which the jaw can be withdrawn from thetooth and leave B free to revolve.

Upon window-sashes the frame is attached so as to bring the leverF justover one of the sash-bars, so as to permit a person about i'to move thesash to place his finger under the bar and his thumb upon F, in order,by pressing them together,`to unlock the wheel B. To the inner face ofthe window-frame, opposite the range of the wheel B, a metal rack Rissecured, whose teeth are tted to those of the wheel. The rack extends sotar as is necessary to insure the appliance of the wheel for thedistance the sash is to be moved.

It will be easily understood from the above description that in whateverposition the sash may be the lever L will block--thatl is, holdand lockit there, and that by pressing upon F and at the same time holding thesash by the sash-bar it can be moved freely a longer or shorterdistance, as one pleases, when by releasing the lever the wheel will beblocked and locked immovably at that point.

The advantages that I consider this mechanism to possess over that ofthe catches now in use are, first, that their rollingv movement makesthem less liable to hitch or work foul than direct-acting teeth orbolts, which must be held `back from their sockets during the raising ofthe sash, instead of rolling or stepping freely into them, as does theWheel or rotary catch, and, secondly, the catch operates as a roller orcaster to assist the sash to free movement upward and downward.

What I claim as my invention, and desire to secure by Letters Patent, is

The rotating catch B, in combination with the ratchet R and thestop-lever L, for the purposes set forth, and substantially as set forthin the above specilication.
